Techniques of duty cycle and other power type modulation of a laser to enable new formation of new designs on textile material.
Description
The cross-reference of relevant application
The application requires the benefit of No. the 60/157th, 904, the U.S. Patent application that proposes on October 5th, 1999.
Background technology
Often handled the clothes of garrha or other material, made their appearances of wear.The consumer has expressed the clothes that require to buy break-in.
The technology of current available this clothes of processing comprises the mechanical sand-blast with sand or other abrasive substance, hand, machinery or from dyanainic friction, and other.Its effect can comprise concentrated wear, its wear patterns below waist below knee portions of leg regions.Other effect is comprehensive wearing and tearing, and the wear patterns that its is described is to the anti-limit of the bottom of s trouser leg below waist." connect the cheek beard " is to be described in during the wearing and tearing term that wearing and tearing takes place along the crease and the flanging of material.Another worn appearance is the rectangular area vestige on the back pkt. of jeans again, and the worn appearance that wallet causes is carried in its imitation in back pkt..Another worn appearance is again called " the edge mill looses ", wherein, the degree of wearing and tearing is so serious, so that exposes other line of cotton fiber.This pattern part even make aperture is arranged on the garrha.Sandblast processes local and all wearing and tearing can be used sand-blast device, make the wearing and tearing of garrha jeans with sand grains or other wearing and tearing medium.This process makes on sand grains fiercelys attack jeans from sand blasting unit.Sand spatially be randomly dispersed in the special outward appearance of generation on the processing region, it is called " penniform ".Wearing and tearing in the featheriness zone are along the periphery of pattern, for example, the edge of pattern and top, to the center of pattern from light change to dark.This unique outward appearance can be imitated the outward appearance of the garrha jeans of the long duration of having worn and torn.
Yet the sandblast process has a plurality of problems and restriction.For example, the process of sandblast or other wearing and tearing medium manifests environment and healthy problem.Generally, the workman need dress protection apparatus and shielding, to reduce the harmful effect that sucks aerial sand.Think that this work is harmful work, may cause higher employee to be flowed.
Reduce with scrappage that the sandblast process is associated in, also may be strict with operator's Personal Skills.Because sandblast operator's technology is very important, so in garrha processing factory, their labour cost is than other employee's work rate height, this just has the additive effect that increases certain labour cost.Actual sandblast process is to take place in a room for other regions shield in the manufacturing facility.
Other environmental problem is also taking place aspect the removing of sand and the processing.
The sandblast process is a wear process, and it causes the wearing and tearing of sand-blast device.Usually, equipment needs annual the replacing, even more frequent.Certainly, this may cause cost, maintenance and the erected cost of adding.
Also have, than difficulty, can not obtain with traditional sandblast process such as the new design along the shadow effect of top that connects cheek beard or bottom.
Generally speaking, because labour cost, material and scrapping and the cleaning of desired environment of being produced, the cost of the sandblast process of every pair of jeans may surpass $1.00.Owing to the variability and the variability of process itself, be difficult to duplicate to another part clothes the definite position of sand blasting pattern from clothes from a laborer to another laborer.
Because the wearing and tearing of the sand on garrha, the sandblast process can also influence tearing and tensile properties of garrha jeans negatively.The sandblast process make garrha tear with pulling strengrth reduce reach 50% so much be not general.In addition, because the uncontrollability of wear process after sandblast, is torn with the variation of pulling strengrth bigger.Some manufacturing plant even need test the tearing and tensile properties of the garrha at the minimum privileged site place of wearing and tearing, with tearing and the pulling strengrth standard by clothes company.
Other method that produces worn appearance manifests their problem.In the situation that connects cheek beard or the diffusing outward appearance of mill, manufacturing plant may rely on labour intensity great, expensive and slow manual friction or with the sand milling journey of nuzzling up, wherein, be applied to garrha connecting cheek beard or grinding the outward appearance of loosing, use such as DREMEL sometimes by manual the wiping with sand milling
TMThe rotation drilling machine of instrument and so on.Except be associated with this process labour cost, this craft with sand milling wipe operate in after the washing often relevant with defective, wherein, on garrha connect cheek beard individually may be very little or too much with the sand milling wiping, cause the lower product of quality.Even with sizable capital investment and limited adaptability, some manufacturing plant even attempted using robotization to avoid these problems with the sand milling journey of nuzzling up.
Although above-mentioned shortcoming is arranged, still keep being extensive use of sandblast and friction process, because the garrha of market demand worn appearance.
This assignee has disclosed the laser process of garrha, for example, at United States Patent (USP) the 5th, 990,444,6,002,099 and 5,916, in No. 961.The outward appearance that these technology use laser instrument to change textile product becomes possibility.

Describe in detail
The system and method for describing is explained a kind of system, and described system is used for producing worn appearance on textile material and/or the clothes made with these textile materials.These worn appearances can comprise the outward appearance of simulation wearing and tearing clothes wear effects, connect cheek beard effect, mill loose effect and any other effect, be to produce on the clothes or on the other products made from textile material, make textile material seem more to resemble the textile material of using.In addition, from these inventions, may be the irreproducible new outward appearance fully of traditional sandblast or friction process.This is to use a plurality of technology of describing in detail to finish here.
First kind of technology used laser instrument.Make the output of laser instrument cross textile material and move.Applied from the outward appearance of the energy change textile material of laser instrument and need not undesirable burning, perforation or especially damage textile material.At United States Patent (USP) the 5th, 990, the basic operation that applies energy from laser instrument is described in 444.
In the system that is disclosed, when laser instrument is crossed material and rule (" awing "), what change laser instrument effectively applies energy, for example, and the energy density of laser instrument time per unit (" EDPUT ").The line of being drawn can be the waveform of straight line or Any shape, yet moving around to another edge from an edge on textile or clothes by laser instrument forms line.
The application introduces and effectively applies concept of energy.This comprises the amount of the energy in a zone that is applied to material effectively.Described zone can be virtually any size or shape." effectively apply energy " and can comprise EDPUT (time per unit energy density), but also comprise sweep trace speed, power level or speed class or the duty cycle that changes laser instrument.It comprises the distance of change laser instrument to material, and this can make laser instrument defocus, thereby changes EDPUT.Can also be included in a plurality of time periods or time applies and effectively applies power, for example, and by applying a plurality of transmission of constant power etc.Effect be than be applied to other zone more multipotency be applied to some zone.
Another unit produces control sequence, and the statistics random character that described control sequence simulation particle distributes is produced such as the sandblast process.This technology is used with user interface program, and described user interface program can be drawn in information on the interface screen deviser.With laser instrument the image on the screen is applied on the material.The such higher laser instrument of system in the past of power ratio that uses on the other hand of described technology becomes possibility.
As mentioned above, what the variable quantity part that laser instrument produces on material was based on material effectively applies energy, as above at United States Patent (USP) the 5th, 990, described in 444, as the time per unit grade energy density of laser instrument with respect to material.EDPUT is relevant with sweep velocity with respect to power, the luminous point size of the laser instrument of material with Optical Maser System.
The laser output of use laser instrument is crossed material and is marked many lines.Line can repeat, that is, and and with the shape of zigzag or triangular wave.According to system of the present invention, when crossing the scanning of materials line, change the grade of EDPUT.That is, some the some place between the terminal of at least one sweep trace, EDPUT is different with online each end.Controller system is by controlling the change of EDPUT grade to the parameter (power or duty cycle or speed or distance) of control EDPUT.
Can change the EDPUT that is delivered to material with diverse ways.First method is wattage or the power that changes laser instrument output in continuous or discontinuous mode.Laser instrument depends on beating back and forth of light in the laser chamber.In some laser instrument, the level of drive of laser instrument itself is variable.Therefore exciting unit 100 is actually variable, to change the power output of laser instrument.Therefore, the first method of the EDPUT grade of change laser instrument directly is controlled at the level of drive of the laser instrument in the emulation mode.
Other EDPUT control does not change actual laser power output, but as an alternative, changes the effective energy amount of densities of the per time that arrives material.Other control of EDPUT is to control by duty cycle.Can periodically turn on and off the Control Driver 198 of exciting unit 200 with the speed of suitable piece.The speed that turns on and off must moving faster than laser.This technology changes the duty cycle of the output of laser instrument 205, controls laser instrument effectively to transmit different average power level.In any short time, that is, get in the time quantum of the distance that equals one or two laser beam width time at laser, can regulate duty cycle repeatedly.Therefore can regulate time per unit by this system effectively applies energy density, because the root mean square of power changes in time, just looks like to become power itself.
Laser instrument can also use an adjustable shutter, as is depicted as unit 210.This shutter can use a quick piezoelectric element to open and close the aperture that laser beam 208 is passed through.Mechanical shutter also can at a good pace open or close shutter.Therefore, this mechanical shutter form is the another kind of method that changes the duty cycle that laser applies.
Laser beam is applied on the clothes, and makes it to move with respect to clothes by laser instrument mobile unit 215.This laser instrument mobile unit can comprise moving lens, or changes some other method of laser movement.In the present embodiment, controller can also produce an output of the sweep velocity of control laser instrument.By changing the speed of laser instrument, constant even the output power of laser instrument keeps, EDPUT also can change along its direction of line.
Another method again that changes EDPUT is by changing the output size of laser beam.Fig. 2 illustrates the zoom lens assembly 120 that can electrically control.Controller 199 can produce an output signal, and described output signal changes lens relative position each other, thereby electrically changes the luminous point size.
On the other hand, keep the platform 230 of material itself can move.It is another method again that changes the EDPUT grade that clothes are placed on the curved surface, if the center of described sweep is correct the gathering, then makes laser beam defocus (reducing EDPUT) in the bend office wittingly.
Another method again that changes EDPUT is to carry out a plurality of transmission or laser scanning in the different segmentations of pattern.If all other laser works parameters remain unchanged, those parts that then have a plurality of transmission will have higher effective EDPUT.
Use this system to attempt the process that natural imitation takes place.In some cases, the worn appearance that obtains from the conventional laser scratching process may seem undue unanimity.Can call outward appearance design or that paste to this.Yet purpose is the outward appearance that produces nature as far as possible.
United States Patent (USP) the 5th, 916, No. 461 description probability of use density function turns on and off laser instrument randomly, so that simulation " featheriness " on material.
Yet the inventor recognizes, changes the EDPUT grade in any laser scanning line continuously or discontinuously even can further improve effect.By so carrying out, when laser instrument was drawn each lines on textile material, this system changed to the change on the textile or the amount of wearing and tearing.The invention provides comprehensive control of featheriness degree.So, can stepless control featheriness degree by the EDPUT grade that changes in pattern Anywhere.Can obtain the worn appearance of true appearance with this method control featheriness.
Therefore, textile scanning is crossed by making laser instrument in an aspect of this system, and the use laser instrument changes the color of material and produce the outward appearance of worn appearance or other requirement on textile material, wherein, in a sweep trace, change the time per unit useful power density of a laser instrument at least.
According to an aspect, general inspection is through the clothes of sandblast.This is checked and shows different shape and wear patterns.These patterns are inconsistent substantially in nature.Human overlooker directly or by the robotization checking process, observes the edge of crossing pattern and the height featheriness of top and bottom, or the variation of material (wearing and tearing).Also observe along the different densities of pattern zones of different.Native system from the information stores of this observation in the storer 195 that is associated with controller.This information comprises the geological information about the wear patterns of line.Information also comprises the outward appearance of actual scanning part.
Then, outward appearance is converted to the parameter matrix of particular type.For example, matrix can be EDPUT matrix, power matrix, duty cycle matrix or rate matrix.The inventor found through experiments, and the time per unit energy fluence that is applied to any specific region of some textile can be to change outward appearance with the amount of the energy that is applied with being directly proportional.This ratio must not be a linear scaling.The outward appearance change can also be included in the outward appearance after the cleaning.
For example, therefore can use scanner or the different pattern of camera-scanning.Scanner can be estimated each part on clothes, and the clothes that illustrate here are garrha jeans.System can use the total resolution of scanner, the color of described part to estimate.Can set up a look-up table, the color that described look-up table makes some material and the EDPUT that is applied or power or duty cycle or speed or distance are corresponding.So, can be based upon each regional EDPUT on the jeans.
Can use this information to form above-mentioned matrix, store above-mentioned any parameter.Can use this matrix as the information in storer 195 then, its driving governor is with drive laser.So, the information that obtains of some other material according to the observation can be applied to different EDPUT grades the different piece of textile.
On the other hand, the user can check wear patterns, and the artificially input change (power, speed, duty cycle or distance) in EDPUT, the change in EDPUT be associated along the change in the wearing and tearing of pattern geometry.These technology can be reproduced the outward appearance of any needs, but also can produce new outward appearance fully.
Aspect other, can edit existing outward appearance.As mentioned above, outward appearance is scanned to form matrix.Can edit matrix then, preserve the part that needs, and change other parts.
Can see that the example that distributes along the EDPUT of single scan line is as shown in the Table I.
The EDPUT of a sweep trace of Table I calculates

3After can making these, higher EDPUT is associated with comprising the more progressive wear patterns that mill looses.
Yet, should be described see that EDPUT value can change about 40% and still in other single line, EDPUT can change above 1000%.Certainly, can make the EDPUT value only change 25% or change 2000% so much, the different worn appearance that has different featheriness degree with generation.
Generally, see these values, EDPUT can increase the amount of any requirement.In addition, when described system was illustrated in the scanning EDPUT and changes several times, EDPUT can change any number of times in a sweep trace.Therefore, the control of EDPUT is unlimited, can change to thousands of percentages from several percentage along every sweep trace, and from a sweep trace to other sweep trace.
The inventor observes, and keeps the higher-wattage or the duty cycle of intensity of image by use, with the sweep velocity of 50,000 mm/second, can make cycle length of lase on the wear patterns on the garrha trouser legs reduce to 8 seconds or still less.
Table II illustrates along the variation of the EDPUT of each root sweep trace of different pattern.

This notion of circling round is " gray shade scale " feature of " black and white " characteristic change Cheng Xin of laser instrument line image.In to traditional laser scribing, with constant EDPUT or power or duty cycle generation image such as materials such as wood, plastics, metals.Under the situation of garrha laser scribing,, can produce image by on every line, using constant EDPUT as described in foregoing invention person's the early stage patent.Therefore, at lase with after cleaning, be formed on a kind of uniform color between indigo or black (for low EDPUT line) and white or the grey (for high EDPUT line).Yet the ability that changes EDPUT continuously or discontinuously along any part of pattern allows image to be assumed to any colourity (after cleaning) between indigo and the white.Colourity is associated with the degree of wear or the degree of fraying.Therefore, the ability of control colourity also allows control wearing and tearing and penniform degree.
In addition, therefore this new variable general character allows to produce the impossible complete new outward appearance that produces by any other economic means.Can be created in the outward appearance that frays, image or the complete new outward appearance that have continuous or discrete different chrominance sections between white and the indigo.In other material industry, can have other application in the technology that changes EDPUT during the laser scribing continuously or discontinuously as described herein, in described other material industry, use laser instrument ruling such as wood, glass, plastics, rubber, fiber, steel and other material.
Mention that as top this system has the ability of more correctly estimating worn appearance.This finishes by producing control sequence in turn-on/off state, continuous state, discrete state or in emulation mode, and described control sequence is reproduced desired characteristic.Can provide the controlled quentity controlled variable of any needs, the quantitative limitation of the EDPUT grade that the system that only is subjected to produces.Still can stipulate general EDPUT outward appearance, but also can control during the line EDPUT the accurate point of change place with figure.The EDPUT outward appearance can comprise the percentage of desired peak power or duty cycle.As an example, for requiring zone can select 50% value than less wear, and for requiring the zone than heavy wear can select 100% value.
Disclose auxiliary designer's new technology.This allow the operator to draw on computer screen shape and how much that desired pattern needs, described pattern are to require on garrha lase to obtain worn appearance.In addition, the designer stipulates the degree of featheriness or EDPUT or power or duty cycle distribution.Have, this specification can be the percentage of maximum EDPUT, power or duty cycle simply again.
Each effectively applies power level and is associated with a kind of color.The different piece of drawing pattern with different color content, wherein, color content can be with for example, R, G, B (red, green, blue) level flat-out, or with grey level.In one embodiment, color is associated with the varying level of the duty cycle control of laser instrument.The user draws pattern with mouse on computer screen the shape that needs.The user can select different colours for zones of different then.This can use the user-friendly camera technology or select or select by right click on the zone with from context menu from menu.This is clicked with the different piece of the pattern with different EDPUT/ power/duty cycle level and is associated.The user can be provided with actual power level or the duty cycle that is associated with given color, and can modify for different materials.
Use user interface screen shown in Figure 3 can produce the concentrated wear effect.Fig. 3 illustrates a graphic user interface, and it allows to be formed on line on the clothes and forms the pattern of basic design or the part of pattern.A plurality of different pieces form actual pattern 300.Total outer periphery of exterior section 305 definition shapes.In these parts also just like other peripheries that illustrate such as 310,315,320.Also illustrate such as 325 innermost like this shapes.For such shape of pattern definition pattern of oval shapes, a plurality of parts are concentric garden or half-concentric gardens.Periphery can define these parts.Part of definition space between per two peripheries.On the other hand, each part can define an independently layer.
Fig. 3 also illustrates a plurality of operating parameters that can be provided with.This comprises 330, and its setting unit is the speed of per second inch, and 322, its setting unit is the laser instrument scaling factor of per inch unit.Pattern scaling factor 334 can also be set.Can be arranged on the pattern dimension on the laser instrument.The direction that 338 indication lasers are drawn.340 expression change color.Boundary length is set in 342.For some at random or pseudo-random process, may need random seed.This random seed can be set.General editor's control such as editor, preservation, Pre-testing etc. also is shown.
350 expression distribute power.Color 352 is on the left side, and the distribute power of being expert in 354 is associated with described color.
The user selects shown outermost part or any system start-up during than the inside part.In these parts each can be set, have specific distribute power by a color and part correlation connection that makes color palette 352.Distribute power is represented different laser instrument intensity (EDPUT grade), therefore represents the different degrees of wear.For example, the bright exterior section such as 310 and 305 is associated with lower-wattage duty cycle level.This produces brighter worn appearance.Can make being associated with higher power duty cycle of pattern such as part 325 than dark-part, and the more serious worn appearance of expression.325 can be illustrated in a part of pattern that draws in the knee actuator current amplifier office.At different gray shade (after cleaning clothes) shown in two zones between extreme.These region representations are in the color of pattern part between indigo and whole white by laser process and after cleaning clothes.Show these each in changing with color.Can be with these values of gray scale or panchromatic preservation, and store the part that these values conducts are depicted as the pattern file of left.ppx here.
Pattern file represent by user interface that show with power distribution information editable specific pattern.
Can also use other processing feature to make pattern that outward appearance more true to nature be arranged.Can select the set of tools shown in 360 to realize these functions.First instrument described herein is to be in harmonious proportion function.Can pixel ground of a pixel, or one in a zone is in harmonious proportion regionally.Can select specific region through being in harmonious proportion.The weighted mean value of the color by forming pixel or zone, or the weighted mean value of the color in adjacent image point or zone (for example 8 adjacent pixel or zone) are in harmonious proportion each pixel or zone are calculated average color.The number of pixels that can change the formation weight is to obtain various effects.
Here another instrument of the company's of being depicted as cheek beard instrument helps to connect the generation of cheek beard.The user can the company's of setting cheek beard length and angle, automatically produce the company's cheek beard pattern that can edit after the user then.
" particle " instrument that illustrates is as a part of 360, and it produces " granular " outward appearance.The process of graininess outward appearance is given each pixel and its neighboring pixels voting right.It is how long relevant that the weight of each voting right and pixel have kept particular color to have.For example, term " length " can refer to the unit number of the image in the zone.Have again, when relating to color, answer described understanding, also can use gray scale to watch independent parts in this system.Can also make sign to these parts with other area limit symbol such as shade, point-like.
Another instrument of developing as a part of the present invention is " sand-blasting machine " instrument.Similar with the employed method of " sprayer " instrument " injection " particular color that a plurality of computing machine paint programs provide, the sand-blasting machine instrument is ejected into " increment intensity " on the pattern.In order to continue simulation, when " droplet " from spraying hit the picture surface, the color of being sprayed was just adopted in pixel that hits or zone at every turn.Use the sand-blasting machine instrument, the color grade of the pixel that is hit by the droplet of increment intensity is incremented to next higher grade.The effect of instrument produces a kind of effect, and the effect of this effect is with to spend in given area " sandblast " time quantum relevant.The sandblast of longer cycle causes more pixel to obtain the painted of result, therefore causes bigger effect.
Also can in intensity one removal pattern, use the sand-blasting machine instrument.In this pattern, the color grade of the pixel that is hit changes to next lower strength grade.
By any pattern that uses the simulation of natural wearing and tearing correctly of sand-blasting machine instrument to form.In addition, this instrument is robotization, some common feature of can automatically drawing, and for example, emulation connects the curve, pocket wear patterns of cheek beard and the ladder shape pattern that occurs along the linear slit of wearing and tearing jeans.
If the user dislikes described effect, then " cancel " function and allow one or more function reversings.For example, this can allow to test different sprayings or other effect, attempts whether can obtaining good effect.If can not obtain, then carry out reverse operating.
This system can produce a plurality of different effects.Can use from the communication of the pattern parameter of the laser instrument control computer that designs a calculating machine and develop efficient system.Developed a plurality ofly be used for that computing machine is watched, the form of generation and transmission of graphical image.The form of these files allows the visual complexity (for example, color) more taller than the desired degree of this purpose, therefore, trends towards providing information and details more information and the details that needs than this purpose.
Developed the new file layout that is called as TBF (TechnoBlast form), it accurately transmits these parameters, and these parameters are to become desired image conversion the laser instrument control command needed.
File in " TBF " form can be the position mapping format of matrix.Power level/duty cycle/the EDPUT of each pixel of each value representation in image and other controlling value.Therefore this file layout comprises an EDPUT value, or at least one is worth, and described at least one value representation is applied to the useful power amount of the pixel that is associated with each pixel or as the group of pixels of a cell processing.
Since can be on the grade of a pixel of a pixel canned data, according to identical information, writing laser instrument can write on level or vertical direction, or writes on any other direction for described incident.Can select to write Inbound by picture direction 38.Suppose in the horizontal direction to write, then image is cut into the wide segmentation of pixel.Section 370 illustrates one of wide segmentation of these pixels with exaggerative form.Yet, answer described understanding, not these pixels that draw in proportion, in fact, real pixel can be the size of any requirement.Notice that each pixel such as 372,372 can have different EDPUT grade associated therewith.When laser instrument during, change the EDPUT grade from the picture element scan of a pixel to.
Use this system can produce a plurality of different types of outward appearances.The example of these outward appearances is only described below.Answer described understanding, can easily produce other effect.Can obtain any one in these outward appearances here in any method of Miao Shuing, promptly, plan the special image that in the color that changes textile fibres, uses by authorization, or by real clothes are scanned, and use the effect of scanning to be formed on the information of using in the color that changes.
Fig. 4 illustrates the concentrated wear outward appearance, and on each garrha trouser legs, its somewhere below waistband extends to the somewhere below the knee.White or the grey black or the indigo (intensity than zonule) that change to top along knee, bottom and lateral parts as 404 shown in of the color of worn appearance (after cleaning) from advantage district at the knee Ru 402 shown in.
Fig. 5 illustrates plan another outward appearance in the back portion use of garrha, for example, and in the seat area of trousers.Once more, this part is oval-shaped basically, but some wearing parts are arranged in center 502, and has the less part of wearing and tearing facing to edge 504.
Fig. 6 illustrates the worn appearance completely from waistband to bottom of s trouser leg limit part, wherein, the scope of worn appearance (after cleaning) from along the white the surging zone of the center of pattern and length or grey to indigo or black along top, bottom and the edge of pattern.
Fig. 6 also illustrates the worn appearance completely from back side waistband to bottom of s trouser leg limit part, and wherein, the color of worn appearance changes to the indigo or the black at top, bottom and edge along pattern from white the surging zone of pattern and grey.
Fig. 7 and Fig. 8 illustrate the company's cheek beard worn appearance with many lines, and the width of described many lines is from about 1/8 inch to about 2 inches, 1 to 14 inch of length.The color of pattern changes to indigo or black along pattern edge from the heart white or grey pattern.Connecting cheek beard worn appearance can be along any zone of the front and back of garrha jeans, and can comprise one or several rectangle parts.
In the knee of garrha jeans shown in Fig. 9 and 10, back side seat area, along the bottom of front and back bottom of s trouser leg part or the mill in any other zone outward appearance of loosing.EDPUT has enough values and grinds diffusing garrha, so that exposes other line, or in fact aperture is provided on garrha.
Theory in above-mentioned ' 444 patents of this violation, ' 444 patents are lectured the perforation that does not need by material.Specific " mill looses " effect provides enough EDPUT, causes the damage of material wittingly, yet, be in mode controllable and that need.
Use is simulated the wearing and tearing of the wallet in the pocket in the back along about 2 inches * 4 inches rectangle worn appearance of the back flour-sack of garrha, and wherein, the pattern color around rectangle is white or grey, is blueness or black at the center.Figure 11 illustrates the TechnoBlast logo image that produces for such outward appearance.
Can be combined into single image to these outward appearances any or all of.Can use pool image to garrha jeans lase then.This can represent the additional advantage of native system.In the former system, use different processing to obtain different effects.For example, use traditional sandblast to be created in the concentrated wear of garrha bottom of s trouser leg front and back.Make and wipe sand by hand and operate the company's of formation cheek beard, wherein, each laborer produces the various cheek beard patterns that connect.Make the diffusing outward appearances of formation mill such as wiping the sand drilling machine by hand.Yet, in native system, in identical file, can comprise all a plurality of effects.For example, Figure 12 illustrates the composition file that comprises a plurality of effects that illustrate above.As shown in Figure 12 1202 other effect is shown, wherein, connecting cheek beard is shade.Just in time on connect cheek beard or the color of lower part be white.This is illustrated in the described zone does not have lase, causes that described zone is the garrha blueness after cleaning.Connecting cheek beard itself can have different colors, to produce different featheriness effects.For the company's cheek beard that very needs, this technology produces the effect of shade.
Be intended to material is made sign for the type of laser instrument, such before system used quite lower powered laser instrument, for example, from 25 to 100 watts.Used the laser instrument of making sign, with at plastics, wood, steel and formation graphic image on glass and text.Be referred to as the higher power of the general generation of laser instrument of the other type of laser cutter, for example, 250 to 2500 watts.The problem that the inventor notices is the cycle length that applies wear patterns.When using low power laser, for apply at every turn, the order of magnitude of cycle length may be several minutes.
Should be with describing the more use of superpower laser, for example have the laser instrument of 250 watts or higher power level, preferably 1000 watts or higher power.For example, may be several minutes the cycle length with 50 watts the laser instrument wearing and tearing garrha jeans of generally making sign.500 watts laser instrument can produce identical pattern in the several seconds.Yet this 500 watts laser instrument is general only to be used in cutting operation.Expect not damaged material by mistake of these higher-wattage laser instruments.Yet,, can use the higher-wattage laser instrument safely by regulating EDPUT.
As a special example, compare with 2 minutes sandblast process of needs, the inventor can use 500 watts of laser instruments in 15 seconds in front with aft section on the lase wear patterns.Also it is contemplated that and use 2500 watts of laser instruments to applying the zone, this will further reduce cycle length.
Initial duration of test at superpower laser has carried out other exploitation.The problem that will note is that online line begins the place, and desired power level or duty cycle can be referred to as toning here than desired height.The physical features of laser procedures require when from power or duty cycle change to the higher level of power or duty cycle than low level the time, " inertia " of power may cause desired higher power of power or duty cycle toning when initial or duty cycle.
This may cause the excessive initial visual effects on the garrha target.When in fact laser instrument being adjusted to connection from turn-offing (zero energy), this effect may be the strongest.When using the laser instrument (for example, 500 watts or higher) of higher-wattage, it is more obvious that the effect on garrha becomes.
In order to overcome this problem, use the border solution.Give desired pattern " border " zone.Laser power is arranged to level x, and described level x is high as much as possible, but can not cause any visible effect on the garrha or on other dress materials.The output of laser instrument is delivered on the position of outside, border.Because laser instrument is in power level x, this can not cause visible variation.When laser beam enters desired visual effects zone, increase the useful power level.Increase less useful power level this moment, because be to be increased to desired level from x, rather than is increased to desired level from 0.So, can reduce the toning that causes owing to initial connection.
Should be based on the interference of the stitch of pattern/line of marking according to laser instrument and material with another key character of noticing.Laser instrument writes can produce alternately between the direction character of the frequency of feature, laser instrument and material some unwanted " interference pattern ".These direction characters can comprise any aspect of asymmetric material, and are special, can comprise cutting, filling and the twill pattern of garrha fiber.The rotation of fiber or line direction can change this effect.When hope reduces this effect, make the material orientation, cause sweep trace and cutting, filling or twill pattern at an angle of 90, so that described effect minimum.Yet some interference pattern itself makes the garrha jeans produce very interesting outward appearance, and may be desired.Therefore, this system aspect comprises the mutual effect between the direction character of considering laser scanning and material.
Therefore, another parameter request of this system is placed the directional patterns of material with specific orientation.Also can control by using control 338 to change the picture direction.Others are used the cameras view system of given side to material, with the direction character of test material automatically.Then, these feature input computing machines, and as an operating parameter use.
As mentioned above, when simulating nature wore and tore, the utmost point wished to avoid artificial and outward appearance design.Therefore, the chance minimum that makes human eye discover any systematicness in the pattern of laser instrument generation is useful.A method that reaches this point is to allow user's specified power level in design, but determines the accurate point that the power between two contiguous level changes randomly.Not to need this feature all the time.Therefore, the randomization of power level change is that the user is optional.
The higher-wattage laser instrument can be worked comparatively fast, and therefore the process from more robotization obtains benefit.Transfer system shown in Figure 1 provides garrha jeans 100 on certain template 102.In the horizontal direction the garrha jeans are introduced laser instrument.Laser instrument carries out the line to worn appearance then, thereafter, makes the second jeans shown in 110 remain on its back, and introduces and carry out processing then.Handle by this way after a collection of jeans, can take off them from template, turn over and carry out the line of worn appearance with identical or different laser instruments on overleaf.Fig. 1 also illustrates in-line material handling system, comprises in-line car washing installation 120, for example, has the system that brush applies washing powder, and one is taken off system, for example wet vacuum 130.This can use the parts from the carpet purging system that can obtain in enormous quantities, for example, and the carpet doctor
TMOr similar washing powder/vacuum combination, can produce desired effect with in-line system.
Fig. 1 illustrates the straight line path conveyer belt system.Yet, it is contemplated that the collar plate shape travelling belt.
Other system shown in Figure 13.Jeans 1300 are placed on the template shown in 1302.By some way jeans are remained on the template, for example, use clip inside, shown in 1304,1306.These clips remain on the position on the template garrha jeans.Each template also comprises the swingle 1308 that is connected to spinner 1310.Transmit jeans along forwarder 1312, described forwarder 1312 comprises at least two in these spinners, and second shown in 1315.At the primary importance place, jeans contact with first laser instrument 1320.This laser instrument produces worn appearance in the front of jeans, shown in side 1.After so carrying out, spinner 1308 rises, and causes jeans to be turned to side 2.Then, side 2 contacts with second laser instrument 1330, and described laser instrument is rule to the worn appearance of back.After handling, take off jeans from template, and new untreated jeans are applied on the template.When using two laser instruments to describe these systems, should described understanding, can use single laser instrument, that is, rule in the front of one or more jeans, then all jeans are turned over, and rule in the another side.Whether a kind of automated system can detect handles the front and back, for example by making the clothes imaging, and seeks label or bar code on jeans.Can on the specific region such as waistband, plug a video camera observing system at every turn, and regulate laser scanning simply at every turn to guarantee that image is on the correct position on the jeans.
Figure 14 illustrates another kind of system again.Remain on the certain location by be added in the side that makes jeans on the clip region with clip, for example, jeans are handled the inside of the pocket that takes place minimumly.It also may be other clip region.Material handling system carries jeans by clip region, for example, and by the wire rod that moves continuously.
On the other hand, can use a kind of form of type shown in Figure 13 as the vertical conveyer belt system of freedom.In this embodiment, use twin-laser, a laser instrument marks worn appearance at the top on the top surface 1400 of jeans, and another laser instrument 1420 is in the bottom, marks worn appearance in the lower surface of jeans 1405.For this can use the vertical conveyer belt system of any freedom.For example, this also can realize by the suspension that clothes are hung in vertical direction.Different shape of template can also be arranged.
Type according to employed template can obtain dissimilar worn appearances.For example, similar such as the worn appearance that the general metal form that uses in the dry-cleaning industry produces to the worn appearance that obtains from sandblast, because clothes are quite smooth when laser instrument marks worn appearance on clothes.Yet, use uneven spherical template, such as employed in some jeans finished product factories, can produce some different worn appearances.Spherical template in jeans bottom of s trouser leg the inside is uneven, causes fiber to stretch.During ruling, the jeans of parcel template are the forms that is recessed into.
The inventor notices that the present invention has in generation and connects cheek beard pattern to simulate along representing advantage in the folding line of thigh and knee portions of leg regions.The jeans fabricator had tested a plurality of methods, to produce the desired cheek beard pattern that connects.A plurality of people notice, have only the manual sand of wiping to be only and really can to accept to connect cheek beard worn appearance really to produce.The labour intensity of this process is big, and the quality of company's cheek beard pattern is the function with sand labourer's skill of the company's of clashing cheek beard on garrha.Can expect, have considerable variability to another laborer from a laborer.Some laborer is firmly too big, and some laborer is firmly too little, and the quality that causes final products is that variation is sizable.
Yet the inventor notices, uses the new technology that changes EDPUT along each line, can correctly duplicate company's cheek beard pattern of any needs.In addition, compare, can in the several seconds, be applied on the garrha jeans typically connecting cheek beard pattern with the present invention with manual several minutes of wiping the sand operation.To another garrha jeans, the quality of the company's cheek beard pattern that produces from this system is constant from garrha jeans.Therefore, compare, expect that output will improve widely with the operation of manual wiping sand.
Though only disclose several embodiment, also have other modification, and plan to be included in the following claims.For example, consider that other makes tag unit, this is that except laser instrument other made tag unit.
